Patented May 1Q, 1907.

Amlientien filed Mey 27, 19D5. Serial No. 252,588.

Be it known that l, BERRY A. sxrnn, n, citizen nl" the United States of America., :nid e resident ol' Mansfield, lichisind county, Ohio, have invented certain new and useful lmproven'lents in Valves, of which the iollowing is n speeilinetion,

My invention relates to s combination needle valve er inver cock and n regulator end is adapted te he used in the consumption of gases for fuel and light.

it is well known to those engaged in the manufacture of the various devices used in the consumption of grises that it is neeessfery in order to secure the greatest eiiieieney and economy to provide s mertns of regulating the supply sind delivery of the gas te the burner to conform to the pressure in the meins, which vsries in diderent localities, seeording to the nature of the gas (naturel or strtiiicisl) end the process used in the menuieeture und delivruy to the consumer. An other desirable feature in the construction et' s valve is to afford facilities for regulating the admission end flow of the gss to the burner according to the pressure irrespective oi the needle valve or lever cock end permitting direct, constant and uniform flow end communication With the burner when the needle valve or lever cock is open.

rThe objects of my invention ere to construct e vulve and regulator in such s, manner es to provide e Ineens of overcoming the dissdvsntsges incident to the use of the ordinary valves in different localities with verying pressures and to regulate the admission of the ges independent of the needle valve or lever cock.

Another object of my invention is to permit the i'low and passage of the ges through the valve in such s manner ss to deliver it directly into the burner in uniform and proper quantities and at s point Where the greatest efficiency of the mixture of ges and air is obv tained.

A further oh'eet is to provide e, ineens of cleaning the vslve and it's connections that is simple and eiiieient without removing or disconnecting the burner from the supply pipev I attain these end other objects hy the rneel'isi'iism illustrated in the accom snying drawing in which the figure is an e evation in cross-section showing the application in detsil of my device to en ordinary angular needle valve.

i i I i 1 l i s l l Simile:- liglires rel'er to similer throughout the several views.

Referring te the drawing" (l) indicates body portion of an singular vulve which is mede integral with the regulator (2). An 'niiet pipe (S) is mede integral or connected to the valve with the aperture (4) eommumeeting with the valve chamber (5). The regulator is provided with e screw threaded aperture adapted to receive and engage with the threaded exterior of the regulator needle (35 lesving the tapered end (7) extending into the chemher (8) alined with the seat (9) formed in the end ofthe reducer (10) and communicating with the oriice (11). The regulator needle can be adjusted to conform te the pressure in the meins. The reducer is inovshly secured to the hoilovv screw threaded projecting end (l2) oi the regulator. An ordinary needle valve stern (13) with s suitable operating Wheel (14) having a portien (l5) mede smaller in diameter with its end (i 6) tapered is Vfitted to the inner screw threaded portion of the vslve'ehainber (5) providing e means of adjustment permitting the valve to be opened or closed more or less ss desired. The tapered end (1(5) is adapted to close or partially close the oriliee (l 7) which communicates With and permits the passage of the gas into the chamber (S).

The operation of my device is es vfollows The gas is admitted through the aperture (4) in the inlet pipe thence to the valve chiunber (5) and passes through the oriiiee (1?) into the chamber (8) of the regulator. T he needle vslve is used to shut oil' or partially close the oriiiee (i7 which in a manner regulates the supply 0r pressure of gas but in en unsatisfactory manner es the quantity of gas or pressure is increased es the operating Wheel is turned to open or close the valve. The regulator oovistes the disadvantages sind defects incident to the use of the ordinary valve as it is independent of lthe valve sind its mechanism. lt will he observed that the regulstor pin can be adjusted to permit the ilev: of more or less ges to the burner eceording te the pressure or qusntity it .is desired te use in order to mix properly for combustion irrespective of the pressure or flow in the meins. Especial attention is directed to the isst that the operating wheel or lever which controls the valve een he opened or turned back any number of times without afeeting the quantity suppiy or pressure of the parte IOO gas as it is regulated by the regulator independent of the valve. lf it is desired to clean the orifice in the reducer the pin ((3) can be removed with an ordinary wrench and a brooinstraw or other article can be inserted in the orilice as the opening is in direct alinenlent with the regulator chamber, thus it will be observed that it is not necessary to reniove the burner in order to clean. the orifice as is connnon in the use of the ordinary valves.

Having thus described my invention what l claim as new and desire to secure by Letters Patent is* The combination of a gas regulator and valve, comprising a body portion with an. inlet aperture and a longitudinal portion inade integral therewith forming a valve chamber, an inclined passage leading froin the inlet aperture in the body portion into the valve 2o chamber, a regulator adjustably 'fitted to said longitudinal portion, a screw-threaded plug with a reduced aperture formed tberein litted to the o en end of said chamber, a tubular portion 'ornling a valve chamber rnade integral with the body of the 'valve projecting downwardly at an angle with the body corres )ending to the inclined passage, a needle valve having a reduced extremity adjustably litted to said tubular portion and adapted to close or vary the size of the inclined passage.
